La surprise stratégique. De la notion aux implications
Accroche

The concept of strategic surprise has rarely been defined precisely and generally conveys the idea of a badly or non-anticipated threat which unexpectedly hits a state, shaking its conceptions and its position towards security. Until the 1980s strategic surprise would take the form of a nuclear surprise attack. In the 1990s, the idea of a so-called "computer Pearl Harbor" was put forward, which would neutralize the complex systems supporting western societies. With the 9/11 attacks, the threat of a strategic surprise suddenly materialized. After delineating the legitimate scope of the notion of "strategic surprise", highlighting the variability of its effects and underlining the importance of the "target" and of its vulnerability, this paper aims exploring some possible trails and answers, which would attempt to reduce not only the probability of an attack but also its impact.

Heir to a tradition dating back to the founding of Ifri, the Security Studies Center provides public and private decision-makers as well as the general public with the keys to understanding power relations and contemporary modes of conflict as well as those to come. Through its positioning at the juncture of politics and operations, the credibility of its civil-military team and the wide distribution of its publications in French and English, the Center for Security Studies constitutes in the French landscape of think tanks a unique center of research and influence on the national and international defense debate.

From Corsairs to Private Military Contractors. Nonmilitary Maritime Actors and the Historical Continuities of Naval Warfare

Date de publication
26 August 2026
Accroche

Since late 2023, several Houthi attacks on commercial shipping have involved privately contracted armed teams conducting defensive engagements and coordinating immediate response efforts, often in the relative absence of regular naval forces during the immediate hostilities at sea. These cases highlight a strategic tension that increasingly confronts modern navies. On the one hand, they are expected to conduct persistent, low-intensity maritime security tasks such as counterpiracy, maritime policing, and the protection of commercial shipping. On the other hand, they face renewed pressure to prepare for high-intensity conflict against peer and near-peer adversaries amid the return of great power competition.

Framework Nation: A European Challenge and French Ambition

Date de publication
10 June 2026
Accroche

First appearing in the early 2000s, the framework nation concept follows several distinct rationales, whether it refers to a country assuming the leadership of a military operation, directing a multinational capability project, or commanding a permanent force structure. In every case, the country that takes on this role fully intends to derive from it additional politico-military influence.

23 July 2026
Accroche

Public sentiment is something decision-makers must contend with, especially in democratic states. However, the extent to which public opinion shapes foreign policy varies. Three Council of Councils experts in France, India, and Nigeria reflect on how public opinion does—and sometimes does not—affect foreign policy decisions.

Over the past ten years, NATO has held almost as many summits as it did during the entirety of the Cold War. Are they still useful, or is it time to stop holding annual meetings?
